CRUDE-OL BURNER.

Specification of Letters Patent.

latented March. 6, 19L6.

To all whom it nung; concern:

Be it known thatI, EDWIN DARBY, a citizen of the United States, residing at Iowa City, in the county of Johnson and State of Iowa, have invented a new and useful Crude-Oil Burner, of which the following is a specification.

This invention relates generally to oil-burners, and more particularly to that class thereof known as retort vaporizers, and in which the oil is not only thoroughly vaporized before being ignited, but is also commingled with a certain amount of superheated air and steam.

The object of my invention is to provide a simple and highiy eicient form of burner which can be used in either a cooking or heating stove and one which can be used for burning oil in either a crude or refined state.

With these objects in view my invention consists, essentially, in the employment of a ring having a plurality of o y enings, a flashpan hinged to the ring and a a ted to occupy the central o ening space in t e said ring, a hood adapte to rest above the iiashan and having a central opening surrounded y a depending col-lar, said hood being supported 1oy means of a lurality of air-trunks preferably integral wit the hood, said trunks intersecting or meeting each other at the center of the hood, an oil-sup ly pipe leading into the said trunks and hoo at the intersection of said trunks, and a water-coil arranged within the hood, the supply end of said pipe dprojecting ulpwardly through the hood an the disc arge end of said ipe being connected to an oil-supply pipe w ereby the steam will be mixed with the oil rior to the mixing of said oil with the air winch passes through the airtrunks, the lower ends of said air-trunks resting in the openings produced in the circular ring.

The invention consists also in certain details of construction and novelties of combination, ali of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this speciication, Figure 1 is a perspective view of an oil -burner constructed in accordance with my invention. Fig. 2 is a vertical sectional view. Fig. 3 is a top plan view of the pan. Fig. 4 is an inverted perspective view of the hood and the air-trunks connected thereto.

Fig. 5 is a detail perspective view of the {lashpan. Fig. G is an inverted perspective view of the ring.

In constructing a burner in accordance with n1 invention I employ a circular ring A, whic is ada ted to rest upon the grate at the bottom of t e stove, or it may be supported in the stove in any other suitable manner. This ring has a plurality of openings B, arranged at regular intervals, there being four such openings shown in the drawings, and said openings are rectan ular in shape. A pan C is hinged to the un er side of the ring, as shown at C in Fig. 2, said pan having an outwardly-extending iiange C, which engages the under side of the ring, also most clearly shown in Fig. 2. The panC has a conicalshaped bottom, the apex C3 extending slightly above the sides of the pan and coiied upon the bottom in convoiute form is the asbestos wicking I). The pan C is hinged to the ring, so that it can be dropped down for the purpose of cleaning or removing any sediment that might accumulate therein. The hood E, circular in form, is supported above` the pan C, said hood having a plurality of hollow airtrunks F integral with the exterior thereof, said air-trunks being essentially right an lar in shape, the horizontal members gra ually tapering and converging or intersectin at D', and the uprights members of the sai air-trunks fit into the openings produced in the ring A, and thus conveying the air from the bottom of the stove to the center of the oil-burner. The hood E has a central opening E', which is located at the conjunction or intersection of the air-trunks, said o ening being surrounded by a depending col ar E2, said collar tapering or being contracted, the contracted end thereof being arranged adjacent the a eX of the conical bottom. A. water-pipe Gp passes through the top of the hood and is coiled several times in a convolute form the coils of the ipel resting directl beneath the hood, and tlie discharge end Gy of said pipe is connected to the oil-supply pipe H by means of the union H', the delivery end of the oil-pipe passing into the air-trunks at their intersection or conjunction.

From the fore oing description, taken in, connection witn t e accompanying drawin s a Win be understood that the @s is erst fge through the pipe H and drops upon the con- IOO ical bottom of the flash-pan and is absorbed by the asbestos wicking. This oil is ignited and the water vaporized, the Water passing through the coil-pipe G, arranged in the hood, and the steam passes upwardly and mingles with the oil, wh ich continues to flow through the pipe H. In the meantime the air is being drawn through the air-trunks and commingles with the mixed oil and steam, thereby producing a fuel-vapor, which becomes ignited at the central opening of the hood and produces an intense heat.

The burner is constructed in such manner that there are no parts likely to get out of order and the commingling of the air, oil,vapor, and steamis accomplished in an easy and convenient manner at the pro er time.

Having thus fully descri ed my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. An oil-burner com rising a pan, a hood having integral air-trun s by means of which the said hood is supported, said air-trunks communicating with the central opening in the hood, the oil-pipe leading into the airtrunks, the water-pipe arranged between the hood and pan, and connected with the oilpipe, as set forth.

2. An oil-burner comprisin a pan, a ring surrounding the said pan an having a pluralit of openings, a hood having integral airtrun s, the delpending legs of whichit lnto the openings in t e ring, the horizontal portions o said air-trunks converging at the center of the hood, said hood having an opening at the convergents of the air-trunks, and the Waterpipe arranged Within said hood and connected With the oil-pipeleading into the air-trunk, as set forth.

3. An oil-burner comprising a ring having a plurality of openings, a pan hinged to the said rin and havin a conical-shaped bottom, a hood aving a lurality of air-trunks, the depending legs of) which are adapted to fit into the openin s in the rings, the horizontal members of sai air-trunks converging at the center of the hood, said hood havin a central opening surrounded by a de en ing collar, and the water-pipes arrange Within said hood and connected with the oil-pipe as set forth.

4. An oil-burner comprising a ring havin a plurality of openings, a pan hinged to said ring and having a conical bottom, ahood having the air-trunks integral therewith the de'- pending legs of said air-trunks fitting in the openings in the ring, the horizontal members o said air-trunks converging at the center of the hood, said hood having a central o enin said o enin being surrounded by a epen ing co lar w ich collar tapers toward the apex 3 of the conical bottom, an oil-pipe leading into `the air-trunks at their conjunction or lntersection, a water-pipe assing through the top of the hood and colle beneath the hood, the discharge end of said Water-pipe bein connected to the oil-pipe, and asbestos wicking arranged upon the conical-shaped bottom of the pan, as set forth.

EDWIN DARBY.
